wnIs'r B nnQ Application filed. September 2 This invention relates to-wrist bands and more particularly to locking means therefor for insuring against unintentional separation of the band sections. Y

The objects of this invention are toprovide simple, efiicient, convenientand' inexpensive means for adjustably securing the sections of a metal wrist hand against accidental separation from each other.

Further ob ects or advantages will become apparent as the description proceeds.

The invention consists in the construction,

Fig. 4 is a detail view of the finger catch Fig. 5 is an edge elevation thereof; Fig. 6 is a fragmentary detail perspective view of the retaining. loop fixed to one end of one of the band sections and shown partly in vertical section and broken and dotted lines; Fig. 7 is a sectional view taken on a plane corresponding toline 7-7 of Fig. 1;

, Fig. 8 is a detail view in perspective show ing the;' end of the band section carrying the finger catch; and

clamp. V I I i In the embodiment of my invention as illustrated and which shows a preferred construction I provide a wrist band or bracelet comprising band sections 9 and 10, made of suitable material but preferably of flat metal; I Tubular portions 11 on one end of band sec-. tions 9 and extend between the lugs 13 integral with watch case 14 and receive the usual detachable pin bars 15. End 16 of band section 9 has a perforation 17 and a communicating reduced slot '18 therethrough forming an opening or key slot for receiving a double headed stud 19 adjustablyretained on band section 10. Said band section 10, as shown in Fig. 1, has a plurality of spaced longitudinally arranged holes 20 therethrough adapted to I align with slot 18 in end 16 of band section 9.

Fig. 9 is a perspective view of the spring 8, 1927. Serial N0. 222,628.

Spring clamp 21 frictionally engages the innor face 24 of band section 10. Recess '22, formed in said clamp, engages reduced head 25 of said stud 19, thereby adjustably securing said stud 19 within any one of the desired holes 20 in the band section 10. Said stud 19 is provided with an. annular groove 26, the bottomof which isof a diametersuch as to be slidably received in slot-18. End-27 of band section lO is provided with a retaining loop 28, which is securely attached thereto in anysuitable manner, as for example, by'small rivets 29. The outer end 16' of band section 9 is provided with a finger catch 30, which I catch is soldered to said -endin the position clearlyillustrated in Fig. 8, or it may be an integral part of said section 9. End 16 of band section 9 is provided with raised portions or obstructions 31 oppositely disposed on each side of slot 18, which obstructions. serve to retain headed stud 19 within the closed end of slot 18, thus preventing said stud 19 from accidentally working its way into alignment with perforation 17 and thus allowing saidband sections to expand or separate from one another, as shown by Fig. 2.

' To operate my improved band,'a'ssume that it is in the position shown in Fig. v1.

To expand the band sufficiently for placing it upon the wrist of the wearer over the hand,

simply place the thumb or finger nailagainst the edge 32 offinger catch and push said finger catch and band section 9 in a direction away from said stud 19. This will causesaid obstructions 31 to 99 'pass beneath head 32 of headed stud 19 and allow. said stud to be aligned with perforat1on 17 whereupon said stud may be removed from engagement with end 16 of band section 9 and said sections 9 and 10 drawn apart or expanded until loop 28 engages or strikes against finger catch30 whereupon the band thus expanded willpermit the ready withdrawal of the hand therethrough. To

adjust said headed stud 19 from one of the holes 20 to another (to adapt said band to different sized wrists) simply remove spring clamp 21 from engagement with stud 19 by forcing it edgewise so that the stud will disengage therefrom through slot 21, remove said stud and insert it in the desired hole 20 and then replace said clamp in holding relation' with said stud.

An advantage of this invention is that once the stud 19 has been locked within slot 18, as by obstructions 31,- it is held against accidental separation.

My invention is capable of modification without departure from its scope or spirit as defined in the claims, as for instance, the band may be "formed in one section as when used a bracelet, or it may be formed of a plurality of sections, such as'shown.

What I claim as new and desire to secure by Letters Patent is:

1. Means for detachably connecting the overlapping end portions of a metallic band having a hey-slot in one overlapping end portion and comprising raised portions on opposite sides of thenarrow portion of said slot and in spaced apart relation from its closed end; in combination with a headed stud attached to the cooperating? overlapping end portion whereby said-head-is adapted to pass through the enlarged end of said keyslot and be moved longitudinally past said raised portions and whereby sa-idraised portions will trictionally engage the edge of said headto hold it between'said raisedportionsand the closed-endot-the narrow portion of said slot and whereby said overlapping portion'saie held'i'n detachable relation with each other. v

2-; Means of the character described for adjustably mounting a headed stud in any one 0t aseries of holes in the end portion of amet-allic band comprisinga stud having a head provided with an annular groove and having-a shank adapted to enter any one of $2t'l(ll10l S,"\Vlth a reduced head on'said shank,

to the cooperating end portion whereby said head is adapted to enter'the enlarged endot' said key-slot and be moved longitudinally past said obstruction and whereby said ohstruction will detachably hold said head be tween said obstruction and said closed end, for the purposes specified.

4. Means oi the character described for tor detachably connecting the overlapping end portions of a metallic band having a key slot in one overlapping end portion and comprising an obstruction adjacent the narrow portion of saidslot and in spaced apart relation from its closed end, in combination with a stud adjustably'mounted in any one of a series of holes in the cooperating overlapping-end portion,- said stud having a reducedhead, and having a headprovided with a groove adapted to receive the walls of the narrow portion of said key-slot,-and a-dislied slotted spring clamp detachably mounted be tween said band and the reduced head of aidstud, to? the purposes specified, L

5. Means of the character described for adj ustably mounting a stud in any one of a series of holes in the end portion, of a insanlic band comprising astud liaviiiga shank, a head on one end of said shank adapted to enter any one of said holes, a head on the other end of said shank; in coiiibinati'on with a resilient dished slotted clamp to receive said second head whereby said'stud'is"adapt} ed to be securely but detachably held ad justedposition in any oneoi saidlioles'.

6. Means of the character described for atljustablyv mounting a stud in any one" are series of holes in the endportionfot a metallicbandv comprisinga stud having a shank,

a head on one end of said sha'nk adaptedto enter any one of; said holes, a head onth'ef other end ofsaid shank combination with a resilient dished slotted clamp to receive said second head whereby said stud is adaptf ed to be securely but detachably held in ad justed position in any one of said holes; and a linger catch on one end of saidband; sub stantiallyas specified.
